Add Workdays in Excel

To add or subtract workdays days from a date, respecting holidays but assuming a 7-day week: you can use the WORKDAY.INTL function with an argument that tells it how many days should be subtracted/added as well as which specific holidays to ignore. In our formula below C2 for this example:


Add workdays no weekends1

With this formula, you can have a Thursday evening deadline instead of Monday afternoon! This means that all days in the week are treated as working hours. With two holidays  in range A7:A8  and weekends set using the special syntax “0000000“, your work will be done by 5/29/2022, at midnight PST.


WORKDAY.INTL allows you to calculate a date in the future or past that respected holidays and weekends with its special codes for designating which days are considered as such, but using masks is more flexible since it allows any day of the week to be designated into being treated like weekend ones & zeros!

You can calculate the number of days required to complete your project in an official workplace with this handy formula. Simply multiply Saturday’s total hours by 0,8 and add it onto Sunday-Friday count!

To add days excluding weekends, simply do the following:

Type this formula =WORKDAY(A2, B2) into the blank cell, and press Enter key to get your answer.

Tip: To change the start date of your spreadsheet, simply enter “A2” as desired. This will allow you to input future dates into B2 for each day added on top!

We have now reached the end date, which adds 50 business days, excluding weekends.

Note: The number you’re trying to math is a 5-digit one, so in order for it to show up on your screen correctly formatted as date, click Home > Number Format > Short Date. See screenshot:
